Phases of Decoding
Just as the simple view of reading is a useful organizing tool for considering reading skills, dividing decoding into phases is a useful way to consider decoding skills.
Ehri and her colleagues describe five phases of “working knowledge of the alphabetic system”. Their phases are pre-alphabetic, partial alphabetic, full alphabetic, consolidated alphabetic, and automatic.
These phases are general and descriptive; they are neither set nor universal stages of reading acquisition. Rather, they are categories used to clarify the text-based elements of the complex, interactive relationships among the many influences on reading skills.
This table presents the sequence, content, assessment, and instruction of decoding.
